Rooted in discriminatory gender norms and laws and shrouded in impunity, gender-based violence (GBV) occurs in all societies as a means of control, subjugation and exploitation that further reinforces gender inequality. This publication establishes that these patterns of gender-based abuse are observed across environmental contexts, affecting the security and well-being of nations, communities and individuals, and jeopardising meeting Sustainable Development Goals (SDGs). While linkages between GBV and environmental issues are complex and multi-layered, these threats to human rights and healthy ecosystems are not insurmountable. This analysis reveals the complex and interlinking nature of GBV across three main contexts: access to and control of natural resources; environmental pressure and threats; and environmental action to defend and conserve ecosystems and resources. This publication aims to raise awareness and engage actors working in environmental and sustainable development, gender equality, and GBV policymaking and programming spheres to inform rights-based, gender-responsive approaches to environmental policy, programmes and projects.
